SharePoint Power BI Web part

Anonymous

Please look into "known issues and limitation section" of the article which describes how to resolve "sign in" related issue for SharePoint and Power BI web part.

Link: https://powerbi.microsoft.com/en-us/documentation/powerbi-service-embed-report-spo/

It describes "First release for everyone" must be selected to enable Single Sign On (SSO) which avoids the problem.

While enabling the Power BI web part of Sharepoint for other project we faced the problem as mentioned above.

Enabling "first release for everyone" solved it. 

This scenario also contradicts the statement " the user is select for First Release is able to use web part", which is a first release for selected user option.

So which one is the correct option?  Is it released to everyone as asked by Anonymous?

Thanks!
